40th Anniversary of the Cell Phone

On this day in 1973, a man named Martin Cooper unveiled a device that would change the world. What he revealed to the public was the world’s first handheld, cordless cellphone.

To demonstrate his invention, Cooper invited reporters from all around New York to watch him place the very first wireless call. As fate would have it, Cooper would dial Joel Engel, his main rival at AT&T’s Bell Labs to share the "good" news.

This new technology was small and light at the time, measuring 10 inches long and weighing in at a mere 2.5 pounds. Today, that is enormous in comparison to 2013's tiny touchscreen smartphones.
